  <dc:description>&lt;p&gt;&lt;span&gt;Equations and graphs have been devised to correct for the adverse effects of magnesium upon the Na-K-Ca chemical geothermometer. Either the equations or graphs can be used to determine appropriate temperature corrections for given waters with calculated Na-K-Ca temperatures &amp;gt; 70°C and&amp;nbsp;&lt;/span&gt;&lt;i&gt;R&lt;/i&gt;&lt;span&gt;&amp;nbsp;&amp;lt; 50, where&amp;nbsp;&lt;/span&gt;&lt;span class="math"&gt;&lt;span id="MathJax-Element-1-Frame" class="MathJax_SVG" data-mathml="&lt;math xmlns=&amp;quot;http://www.w3.org/1998/Math/MathML&amp;quot;&gt;&lt;mtext&gt;R = {&lt;/mtext&gt;&lt;mtext&gt;Mg&lt;/mtext&gt;&lt;mtext&gt;(Mg + Ca + K)&lt;/mtext&gt;&lt;mtext&gt;} &amp;amp;#xD7; 100&lt;/mtext&gt;&lt;/math&gt;"&gt;&lt;span class="MJX_Assistive_MathML"&gt;R = {Mg(Mg + Ca + K)} × 100&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span&gt;&amp;nbsp;with cation concentrations expressed in equivalents. Waters with&amp;nbsp;&lt;/span&gt;&lt;i&gt;R&lt;/i&gt;&lt;span&gt;&amp;nbsp;&amp;gt; 50 are probably derived from relatively cool aquifers with temperatures approximately equal to the measured spring temperature, irrespective of much higher calculated Na-K-Ca temperatures.&lt;/span&gt;&lt;/p&gt;</dc:description>
